This article lists the classical guitar music in the classical guitar repertoire. It includes baroque guitar and vihuela music, but not lute music. This music is most commonly performed by classical guitarists and requires the use of a variety of classical guitar techniques to play. During the Renaissance, the guitar was likely to have been used as it frequently is today in popular music, that is to provide strummed accompaniment for a singer or a small group. There also were several significant music collections published during the 16th century of contrapuntal compositions approaching the complexity, sophistication and breadth of lute music from the same period. Most Renaissance lute music has been transcribed for guitar (see List of composers for lute). The baroque guitar (c.1600–1750) was a string instrument with five courses of gut strings and moveable gut frets. The first (highest pitched) course was sometimes a single string. It replaced the Renaissance lute as the most common instrument found in the home. The romantic guitar, in use from approximately 1790 to 1830, was the guitar of the Classical and Romantic period of music, showing remarkable consistency in the instrument's construction during these decades. By this time guitars used six, sometimes more, single strings instead of courses. The romantic guitar eventually led to a different type of guitar in Spain: the fan-braced Spanish guitars of Torres, which may be seen as the immediate precursor of the modern classical guitar. In the 20th century, many non-guitarist composers wrote for the instrument, whereas previously only players of the instrument had done so. 16th century 1535-36 Luis de Milán (c.1500–after 1561) Libro de musica de vihuela de mano intitulado El Maestro 1538 Luis de Narváez (1510–1555) Los seis libros del Delphin de música de cifra para tañer vihuela 1546 Alonso Mudarra (c.1508–1580) Tres libros de música 1547 Enríquez de Valderrábano (1500–1557) Libro de música 1547 Enríquez de Valderrábano (1500–1557) Silva de sirenas 1551 Adrian Le Roy (1520–1598) Premier livre de tablature de guiterre 1552 Diego Pisador (1509–1557) Libro de Música de Vihuela 1553 Grégoire Brayssing (fl. 16th century) Quart livre de tablature de guiterre 1554 Miguel de Fuenllana (?1500–1579) Orphénica lyra 1576 Esteban Daza (c.1537–1591) El Pamasso c.1580 Girolamo Giuliani (fl. 1580) Intabulatura de Chitara 17th century 1640 Giovanni Paolo Foscarini (fl. c.1621–c.1649) Li cinque libri della chitarra alla spagnola 1643 Francesco Corbetta (c.1615–1681) Varii capricii per la ghittara spagnuola 1646 Carlo Calvi (fl.
